My First Manual Regen. I'm getting ready for a 250 mile tow trip and wanted to measure fuel mileage, but went out to dinner tonight and %DPF Full was at 80% so I wanted that regen out of the way. About a mile or so before returning home, DPF went to full and a regen started. The wife didn't feel like a joy ride and I remembered the manual regen.
Coolant temp is not an indicator either. Drive the car for about 10-15mins and then pull over but don't switch off. If your idle speed is higher than normal (circa 1Krpm) then the car is attempting to conduct the regen. Drive off again and stay driving for around 25mins. Pull over again and check the idle.
Spray into long drive on motorway at high revs or forced regen see if it clears. Dealer / garage forced regen + code clear. Dpf removed and cleaned ( I had this done after first forced Regen and later fuel additive method failed and car went into limp mode in a 2010 Mazda 3 1.6 here in Ireland €500) have since sold car
Most of the time the truck is regenerating because the DPF filter has become fully clogged overtime. This can lead your truck to need frequent regens, which we want to avoid. If the DPF isn’t the cause, one of these things could be what is causing your truck to regen more than normal: Dirty air filters. Clogged fuel filters.
